shown blow in the fig.
2 Insert the drain pipe. Push the unit back into the cabinet.
3 Connect the wire to the plug as shown below in the fig.

4 Connect the air conditioner to a separate supply line with an appropriate
power plug / circuit breaker.
5 Installation location
(1) Select a place where cool air emitted from the air conditioner circuits
evenly, reaching every part of the room. Make sure that no obstacles
both inside and outside the room prevent airflow.
(2) Where practicable, locate the air conditioner with the lower edge of
the cabinet approximately 0.75m (29.5”) to 1.5m (59”) from the floor.
This usually provides the optimum air circulation pattern within the
room for cooling.
(3) Mounting must be strong enough to support the air conditioner’s
weight and sufficiently rigid to prevent vibration being transmitted to
windows and the like.
In order to enable efficient and trouble-free operation of your air conditioner’s,
connect the power plug of your air conditioner through an exclusive circuit having
a circuit breaker connected to a proper power supply.

COOLING
During summer, when the temperature is very high, maximum amount of
cooling (circulation with maximum cooling, dehumidifying and filtering effect) will
be obtain by turning the selector switch to “HIGH COOL” and thermostat to
position 9 or 10.
AIR CIRCULATION
As adequate airflow is very important for comfort level. When the selector switch
is set to the “FAN” position, the fan is activated to filter air and circulate it without
cooling effect.
THERMOSTAT CONTROL
The function of thermostat is to maintain the room temperature as desired by
automatically switching the compressor “ON” or “OFF”.
The thermostat is set by mean of thermostat control knob. When the room
temperature is higher than the thermostat setting, the compressor is
automatically switched “ON” to provide cooling effect. When the room
temperature is lower, the thermostat setting is automatically is switched off the
compressor to prevent the temperature from falling further.
1. When you wish to lower the room temperature, turn the thermostat control
clockwise in the direction of higher numbers on the dial.
2. When you wish to increase the room temperature, turn the thermostat
control counterclockwise in the direction of the lower numbers.
3. When the thermostat is set to position 6, 7 or 8, comfortable room
temperature can usually be obtained. Please note that it is unhealthy than
the room temperature be lower than 22°C.
4. The thermostat position 11 and max can be used when the room
temperature does not become sufficiently low. This condition may occur
when the horizontal louvers are positioned downward and vertical louver
are positioned toward the left side, choking the cold air circulation over the
thermostat, which causes the compressor to trip quite earlier and desired
room temperature cannot be achieved.
NOTE:
The thermostat controls the compressor only, while the fan constantly circulates
air even when the compressor is turned “OFF”.
IMPORTANT
When restarting the cooling operation, always allow 3 minutes rest time after it
has been turned “OFF”, either by the selector switch or the thermostat. If the
compressor is restarted instantaneously after it is turned “OFF”, an overcurrent

will flow through the compressor. This will electrically disconnect the compressor,
resulting in actuation of a safety device for about 20 minutes.
EXHAUST AIR CONTROL
By setting the exhaust air control switch “OPEN” it is possible to expel the room
air to a desired extent.
AIR DIRECTION CONTROL
When the jet vane control switch is turned to “ON” position, the vertical louver are
activated to sweep air to the right or left alternately to achieve uniform cooling in
the room.
Louvers may be stopped at any position when control switch is turned “OFF”.
The sweep angle may me determined as required. In addition, the sweep can
span either right or left.
Adjustment of sweep angle and direction can be made by selecting the
appropriate holes at the plate into which the connection shaft is inserted. Select a
sweep angle that is suitable to the layout of the room with respect to where the
air conditioner has been installed.
ADJUSTMENT OF THE SWEEP ANGLE OF THE VERTICAL
LOUVERS
The air conditioner is shipped with sweep angle of the vertical louvers set at 60
degrees to the left and right. You can get the desired direction of airflow by
adjusting the sweep angle in the following manner.
Adjusting the left sweep angle (see figure 3).
Insert the connecting rod into the hole ‘A’ on the hole plate. The sweep
angle has been set to the desired left position.
Adjusting the right sweep angle (see figure 3).
Insert the connecting rod into the hole ‘B’ on the hole plate. The sweep
angle has been set to the desired right position.
Turn the jet vane switch to “ON” and the desired sweep angle will be attained.

ROOM AIR FILTER
A moulded filter is provided at the rear of the removable panel. Since the function
of this filter is to filter dust and dirt from the air, clean it regularly before it
becomes clogged with dust. Wash the filter with clean water. If it is very dirty,
rinse it in a synthetic detergent before washing in clean water. Allow the filter to
dry thoroughly before washing in clean water. Allow the filter to dry thoroughly
before reinstalling.
Remove the filter in the following manner (see Fig #4) using the grip port. Pull it
outward to remove it from the front panel. To assemble the removable panel,
insert its left tips into the slots provided in the main panel and force the
removable panel into its seat.
